摘要
A method includes sensing a process parameter to generate a sensor signal that includes a process signal and line noise components, digitizing the sensor signal at a sample rate, detecting line noise zero crossings in the sensor signal, determining a line noise frequency as a function of the detected line noise zero crossings, and adjusting the sample rate as a function of the line noise frequency to reduce an impact of line noise on the digitized sensor signal.
